The berger manual has 6.5x47 lapua data. It lists a start of 31.5 grains of RL-15 to a max of 35.2 with a 90% fill ratio for the 140 vld. Also a starting load of h4350 at 35.0 to a max of 38.9 with a 100% fill ratio for the 140 vld. I have tried h4350 with bergers 140 grain match BT long range target bullet with good results but I do not use it since I cannot find any. The 123 scenars also shoot very well for me with RL-15 and varget, lapua brass and BR-4 primers. I do not have any experience with the 139 scenars. The 123's worked well, so I didn't bother trying the 139's. I'am running a 1x8 twist criterion barrel.
